Peterson spent the past year playing with Haskins and is set to return in 2020 after the team picked up his option, per John Keim of ESPN.
While the opinion of a future Hall of Fame running back carries some weight, the Redskins will have to make their own decision about Haskins' future after a disappointing rookie year. The 2019 first-round draft pick completed just seven touchdowns with seven interceptions in nine games (seven starts), producing a dreadful 26.8 Total QBR.
His struggles were enough to cause the team to reportedly consider finding a new quarterback in the 2020 NFL draft, including Alabama's Tua Tagovailoa.
"They felt like Dwayne was not the guy right now," a source told Safid Deen of the Sun-Sentinel. "They want to bring in Tua, just get it going and compete."
A lot can still change for Haskins but at least he has the support of his teammate.
